BlackBerry - Changes are not getting reflected in my app

Suddenly my changes are not getting reflected when I run my app.

I have tried the following things.

1. Restarted the Eclipse and tried.
2. created a new Eclipse workspace.
3. Uninstall and installed the Blackberry JDE.
4. As I read "Blackberry simulator not creating COD file", I have deleted some java files and images then tried.

Nothing works开发者_高级运维.

Make sure your project is "Activated for BlackBerry" like this:

Next best thing you can do is go to simulator folder in bb plugin and:

• delete < ProjectName >.* files
• run clean.bat

After that, if app will simply not load into simulator, do Alt+B (Project->Build Active BB Configuration) and see in Console (Alt+Shift+Q, C), if there was any errors during rapc execution.
